High TWS

My Boost Marquee's TWS is always 50% or higher, and I get a pretty good signal at home. I was just curious as to whether or not anybody else is experiencing this, and if this phone may have the same TWS bug that my Optimus V had. It's a common problem with CDMA android devices. But I was almost certain it was Android 2.2 and below. My girlfriend's Android on AT&T is always at 0% TWS and she gets EXCELLENT battery life. Far superior to my battery life and she has the Pantech Crossover, which is older than our Marquee's. Thanks for any input.
